The Theory of Relativity was invited by Einstein due to these studies shown through revolutionary by time, motion and light.
The theory of relativity was revolutionary because it showed how the speed at which time happens is mutable
space and time are not discrete entities: time and space and motion (movement through space)
with time comes questions such as how long how fast
to put it another way, imagine you have a twin. You stay on earth, your twin goes into space on a fast rocket ship for 10 years; when they come back, they're a couple of years younger than you are. It even works with aeroplanes: circle the earth, flying low; when you return to your starting point, your watch will be slightly behind. "If you were actually moving at the speed of light (which you couldn't do, but suppose you could)," says Penrose, "your watch would stop altogether." It's a rather more expensive method of age-defiance than Crème de la Mer, but then again, it has the advantage of being a physical law of the universe. (Relativity for dummies)

Examples from the websites, You can Relate to and put yourself in that situation.
In a word, you can't find any one true "at rest". Izzy was the one who told us that. Izzy said that you can't tell if you move or are at rest at any time. You can say that you go and all else is at rest, or you can say that you are at rest and all else goes. It all adds up the same both ways. So we all knew that much from way back when.

you don't need to be in a void to do this test. We move all the time, even as we sit here. We spin, in fact. So they shot some rays off and took note of how fast they went east, and how fast they went west, and so on. Well, what do you know? The rays went just as fast both ways. All ways, in fact. They all went at c, just the same. Not an iota more or less.

Throughout this website I found many examples to make you understand and relate to the theory of relativity. To make you have a better understanding and how you can relate to the theory of relativity I will provide you with many examples.
